5.1. Obtaining Commons Collections

5.1.1. Problem

You need to use Commons Collections because your application makes heavy use of Collection objects, and you wish to use some of the utilities provided by this component.

5.1.2. Solution

To use Commons Collections 3.2.1 in a Maven 2 project, add the following dependency to your project's pom.xml:

Example 5.1. Adding a Dependency on Commons Collections

    <dependency>
      <groupId>commons-collections</groupId>
      <artifactId>commons-collections</artifactId>
      <version>3.2.1</version>
    </dependency>  

If you are not sure what this means, I'd suggest reading Maven: The Definitive Guide. When you depend on a library in Maven 2, all you need to do is add the dependency groupId, artifactId, and version to your project's dependencies. Once you do this, Maven 2 will download the dependency and make it available on your project's classpath.
